API for distributed tracing.
Distributed tracing, also called distributed request tracing, is a technique that helps debugging distributed applications.
Trace represents a tree of spans. A trace has a root span that encapsulates all the spans from start to end, and the children spans being the distinct calls invoked in between.
Span represents a single operation within a trace.
Spans are propagated in-process in the Context and between process using one of the wire propagation formats
supported in the opentelemetry.trace.propagation package.
